No they didn't the whistle blew before the puck crossed the line. No Goal end of story.

Nice try slick -- just re-wound the replay 10 times -- not even close. Krejci pulled the puck out that was clearly over the line. The ref leaning over the net blew the whistle after the puck came loose and slid behind the net. No other whistle from any other ref sounded prior to that whistle.
